2021
SN Applied Sciences
Preserved Fulltext
In this paper, a watermarking algorithm has been proposed based on a lossy compression algorithm to ensure authentication and detection of forgery. ...
In addition, two tamper detection bits are generated based on texture information and pixel location and inserted in the watermarked image. ...
The authors of [17] proposed a non-blind digital watermarking technique to preserve the ownership of the color image. ...
